测量了１６Ｏ＋２３２Ｔｈ、２３８Ｕ和１９Ｆ＋２３２Ｔｈ近垒和垒下熔合裂变截面以及碎片角分布．包含靶核静态形变的耦合道理论解释了垒下熔合截面增强，预言了复合核系统自旋分布展宽．而实验上观察到的碎片角分布各向异性明显与裂变统计理论的预言不一致．
The fission cross sections near the base and base of the 16O + 232Th, 238U and 19F + 232Th and the angular distribution of the fragments were measured. Coupling-path theory involving the static deformation of the target nucleus explains the enhancement of the fusion cross-section under the barrier and predicts the broadening of the spin distribution in the composite nuclear system. The anisotropy of the angular distribution of the fractures experimentally observed is obviously inconsistent with the prediction of statistical theory of fission.
